Large sheets reduce seams, and the QuickSeam Tape system ensures easy, reliable installation without specialized equipment. ## Description Firestone PondGard Features & Benefits Easy to Install PondGard comes in a large variety of panel sizes to match your needs and reduce the amount of field seaming required. When necessary, dependable field seams can be made with Firestone’s QuickSeam Tape System, which requires no special training or expensive equipment to install. High Flexibility PondGard remains flexible in a variety of temperatures, from -45° F (-43°C) to 180°F (82°C), enabling it to be installed year round in a variety of climates and terrain. High Elongation PondGard can elongate over 300%, which enables the membrane to stretch and conform to objects in the substrate. Superior Weathering Resistance PondGard has a documented performance history in exposed applications, exhibiting outstanding resistance to ultraviolet (UV) radiation and ozone. Outstanding Aging Stability PondGard is a non-crystalline material. It contains no plasticizers that can migrate and lead to premature membrane failure due to embitterment and cracking. Fish Friendly PondGard is a specially formulated EPDM membrane designed to be used safely in the presence of fish and plant life. Review: TOUGH STUFF!!!! - This stuff feels like bicycle tube tires. Which may not be descriptive to all people, but lets just say it is nice and rubbery and I wouldn't expect it to tear/puncture easily. No doubt it will tear and puncture with the proper force (we cut excess with ease), but compared to cheap pond liner - this stuff is tough. We bought some much cheaper (cheaper as in $$$) pond liner for a different purpose 6 months... 10 or 15 mil I think. This 45 mil "firestone" stuff is way better (and physically heavier). The cost difference is definitely there, but I didn't feel bad paying the extra $$$ once I experienced what this is vs the other stuff. I doubt I will have another pond in the future, but if I do I will be buying this material vs cheap pond liner. Review: Works great and tough! - This is a tough liner. I've used these liners before in different sizes and I'm always pleased with how well they hold up over years of use. Several of these rocks are pushing 200#'s plus. I did use a Nonwoven Geotextile Underlayment with them but a great liner to create whatever you can envision! ## Features - FISH-RELIABLE 45 MIL FIRESTONE EPDM POND LINER Create long-lasting koi ponds, water gardens, fountains, and waterfalls with this genuine Firestone PondGard 45-mil EPDM liner. Specially formulated for reliable use around fish and aquatic plants, the membrane provides exceptional waterproofing and durability for backyard and professional pond builds. - HIGH FLEXIBILITY FOR YEAR-ROUND INSTALLATION Flexible EPDM material remains pliable in extreme temperatures ranging from -45°F to 180°F, allowing installation in nearly any climate or season. This flexibility lets the liner conform smoothly to shelves, curves, rocks, folds, and varied pond terrain without cracking or weakening. - EXCEPTIONAL ELONGATION & SUBSTRATE CONFORMITY PondGard EPDM stretches over 300%, enabling it to mold securely around roots, stones, and irregular surfaces. This superior elongation minimizes stress points and prevents tears, providing a reliable, durable foundation for ponds of all shapes and depths. - SUPERIOR UV, OZONE & WEATHER RESISTANCE Engineered for long-term outdoor exposure, Firestone PondGard has outstanding resistance to sunlight, ozone, and changing weather. Its proven field performance ensures a long lifespan, resisting brittleness, cracking, and premature aging often seen with low-grade pond liner materials. - EASY TO INSTALL WITH MINIMAL FIELD SEAMING Large 10×20 ft sheet reduces the need for seaming during installation. When seams are required, Firestone’s QuickSeam Tape System offers dependable bonds without special equipment or training. Lightweight, non-crystalline EPDM contains no plasticizers that can migrate or fail over time. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005BY617Q | | Best Sellers Rank | #273,404 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #188 in Water Garden & Pond Liners & Seals | | Brand Name | PondGard | | Closure Type | No closure type | | Color | black | | Customer Reviews | 4.6 4.6 out of 5 stars (110) | | Installation Type | Floating | | Manufacturer | Firestone | | Manufacturer Part Number | 4336413135 | | Material Type | Rubber | | Model Name | 10 x 20 Firestone 45 Mil EPDM Pond Liner | | Model Number | 00000017 | | Pattern | Solid | | Product Care Instructions | Install, maintain, and store in various weather conditions. | | Product Style | Clogs | | Shape | Rectangular | | Size | 10x20 | | UPC | 000000000017 | ## Product Details - **Brand:** PondGard - **Color:** black - **Material:** Rubber - **Size:** 10x20 - **Style:** Clogs ## Images ![10 x 20 Firestone 45 Mil EPDM Pond Liner, UV Radiation Resistance, Black - Image 1](https://m.media-amazon.com/images/I/31+X0kHIlkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ TOUGH STUFF!!!! *by M***E on January 6, 2022* This stuff feels like bicycle tube tires.
